Not everyone can grasp the concept of triangles as well as the many mathematical calculations applied to it, where arguably the most famous of them all would be the Pythagorean theorem. This handy device is supposed to be used to provide you with accurate reading when it comes to designing angled walls and smooth looking interiors. This digital measure will rely on existing laser ray measure techniques to mathematics formula of triangles through the simple motion of measuring a target from afar. All you need to do is swing the arms and use the red light to point towards the couple of ending points of target length, where the result will then show up on the display. No idea on whether this will be practical though as old hands at renovation and home improvement might think otherwise.
